X-WATERS МСК Солнечногорск

Lake Senezh is not a natural depression, but a reservoir carved into the Klin-Dmitrov landscape that dates back to the last ice age. As you glide through its waters, you are traversing a basin that averages between 2.5 and 3.5 meters in depth, occasionally reaching 6 meters at its deepest points. Swimmers often describe the sensation of passing over this shallow, manageable floor as both grounding and surreal, especially when the water remains calm enough to reflect the changing sky. The lake acts as the primary source for the Sestra River, and you can observe the subtle shift in current where the reservoir gives way to the river's flow—a moment that marks the transition from standing water to a moving waterway.

Landmarks from the water

Navigating the perimeter offers more than just distance markers. As you find your rhythm, the shoreline presents a series of distinct visual anchors. To the north, the Church of St. Nicholas, consecrated in 1879, rises above the tree line, its silhouette serving as a silent spectator to your strokes. Closer to the modern waterfront, the Senezh Art Lighthouse breaks the horizon, a functional piece of contemporary design that helps orient swimmers during the longer 10km efforts. If you look toward the nearby Podsolnechnaya railway station, you might spot the 19th-century water towers, relics of the original Moscow-St. Petersburg line that once powered the steam locomotives of the region.

Beyond the architecture, the local environment carries a weight of strategic history. Near the village of Timonovo, the shoreline borders the grounds of the 820th Main Centre for Missile Attack Warning, a facility integral to regional defense. While this site remains off-limits, its presence provides a stark, modern counterpoint to the quiet, ancient history of the lake basin. The X-WATERS event, scheduled for August 1, 2026, offers distances ranging from 50m to 10km, with entry fees between 39.9 and 109.9 EUR. Participants receive a timing chip and a comprehensive starter pack, ensuring that every effort, from the sprint to the double-lap marathon, is accurately logged in this unique glacial environment.
